using pulse shapes other than trapezoids, e.g., 'long-narrow' [1]}, oscillating [2]}, free [3]}, quiet [4]} gradients, as well as numerous compensating waveforms;

using multiple pulses where amplitude, duration or spacing of RF or gradient pulses represents relevant metadata, e.g. DDE [5]}, FEXI [6]}, STEAM [7]}, [8]} or diffusion-TSE [9]};

with different encoding from slice to slice [10]}, [11]}.
